Ok, good points. There are at least three major "front end" experiences,
none of which are exclusive at any location:
1. Squat
2. Sit
3. Urinal
And one fairly critical front-end refinement related to wiping:
1. Toilet paper provided.
2. BYOP (Bring your own paper if you want it)
3. Rag provided (you wash it out yourself)
------------------------------------------------------------------------------------------------------------------------------------------------------------------
Major back-end experiences include:
1. Flush (waste is carried away after each use)
2. Pit (waste remains on site)
But it divides down more than that:
1. Pits
1. unlined pits (waste drops into a hole -- the most common type.
When full, a new hole is dug nearby.)
2. lined pits (waste drops into a vault which is periodically pumped
out)
3. composting (waste drops into an on-site composting vault, with
potential for reduced odor)
4. chemical (a lined vault is filled with a chemical. common on
portable toilets).
5. bucket (just a bucket someone has to remove periodically).
2. Flush
1. Water flushing (clean water is used to help remove waste).
2. Waterless flushing (e.g. Water Free Technolgies)
There's also a squat/sit combo just to jazz things up:

But the important distinctions may be less. I'd be happy with no more than
three categories:
- Flush toilet
- Open pits (where you see the waste)
- Composting (where the waste is continually treated, and often not
apparent)
Thus it might be:
toilets=yes or amenity=toilets
toilets:position=(squat,seat,urinal)
toilets:waste=[flush,pitlatrine,composting,bucket]
toilets:paper=no
fee=[yes,no]
Where a multiple value of "toilets:position=seat;urinal" would be most
common in Western countries.
